Embodiment 1

[0018] The first step, bleaching and softening of loofah: dissolve hydrogen peroxide, sodium silicate and magnesium sulfate in water to form a mixed solution, wherein the volume fractions of hydrogen peroxide, sodium silicate and magnesium sulfate in the mixed solution are 1%, 5-5% respectively. 10%, 0.1%, and then put a certain quality of washed loofah into the mixture, then put the beaker containing the mixture into a heated constant temperature water tank, and bleach at a constant temperature for 1 hour. Rinse, then soak in EDTA solution with a molar concentration of 0.025mol / L for 1 to 2 minutes, take it out and let it stand for about 5 minutes, and then wash it with deionized water until neutral.

[0019] The second step, the alkali treatment of loofah: the loofah after bleaching and softening is put into sodium hydroxide or ethanol solution with a mass concentration of 25% to soak, and in the soaked state, use a certain 400W~700W microwave intermittent radiation for 10min...

Embodiment 2

[0023] The first step, bleaching and softening of loofah: hydrogen peroxide, sodium silicate, and magnesium sulfate are dissolved in water to form a mixed solution, wherein the volume fractions of hydrogen peroxide, sodium silicate, and magnesium sulfate in the mixed solution are 1%, 8-8% respectively. 10%, 0.1%, and then put a certain quality of washed loofah into it, then put the whole beaker into a heated constant temperature water tank, and bleach it at a constant temperature for 1.5 hours, and the bleaching temperature is 70°C, then take it out and rinse it with clean water and put it in Soak in EDTA solution with a molar concentration of 0.025mol / L for 1 to 2 minutes, take it out and let it stand for about 5 minutes, and then wash it with deionized water until neutral.

[0024] The second step, the alkali treatment of loofah: the loofah after bleaching and softening is put into sodium hydroxide or ethanol solution with a mass concentration of 30-45% to soak, and is irradi...

Embodiment 3

[0028] The first step, bleaching and softening of loofah: dissolve hydrogen peroxide, sodium silicate and magnesium sulfate in water to form a mixed solution, wherein the volume fractions of hydrogen peroxide, sodium silicate and magnesium sulfate in the mixed solution are 1%, 5-5% respectively. 10%, 0.2%, and then put a certain quality of washed loofah into it, then put the whole beaker into a heated constant temperature water tank, and bleach at a constant temperature for 0.5~1.5h, the bleaching temperature is 60~80°C, and then take it out with clean water Rinse and soak in EDTA solution with a molar concentration of 0.025mol / L for 1 to 2 minutes, take it out and let it stand for about 5 minutes, and then wash it with deionized water until neutral.

[0029] The second step, alkali treatment of the loofah: put the bleached and softened loofah into sodium hydroxide or ethanol solution with a mass concentration of 35-50% for 12-24 hours, and irradiate intermittently with 400W micr...

Abstract

The invention provides a method for preparing a luffa deodorant and antibacterial insole, and belongs to the field of the application of health-care shoe materials for improving the microclimate of shoe cavities. The method comprises the following steps of: bleaching and softening luffa, and immersing the cleaned luffa into a matching liquid of H2O2, Na2SiO3 and MgSO3 and decolorizing and softening; cleaning, soaking in ethylene diamine tetraacetic acid (EDTA) for a moment so as to avoid yellowing, alkalifying, and soaking in a certain amount of a solution of sodium hydroxide\ethanol to perform delignification and increase the porosity of the surface of fiber; performing intermittent microwave radiation to deepen the treatment degree and strengthen the absorption performance of the luffa so as to ensure that the luffa has a good deodorization function, and adding a prepared antibacterial agent and finishing so as to ensure that the luffa which has a certain antibacterial function has a stronger antibacterial property; and finally, pressing the luffa into sheets, and compounding the transverse and longitudinal sheets according to the trend of the fiber to obtain the luffa deodorant and antibacterial insole.

Description

technical field [0001] The invention relates to a method for preparing loofah deodorant and antibacterial insoles, and belongs to the application field of health-care shoe materials for improving the microclimate of shoe cavities. Background technique [0002] (1) Sweating of the feet during exercise and walking will produce peculiar smell, and the friction between the sole and the skin of the foot will also cause various discomforts. For this reason, people use insoles to absorb sweat, relieve friction on the soles of the feet and weight pressure, and replace the insoles. It can alleviate the problems of foot sweat and odor, but the general insoles have limited moisture absorption and deodorization functions, and need to be cleaned repeatedly, and the wear and tear is obvious. In order to improve the efficacy of insoles, various insoles are applied, such as adding health-care drugs, using fiber materials with better air permeability, etc., but the validity period of the dru...
